Use of the Digital Channel in the MEA2100-System
In contrast to the other MEA- and ME-Systems from Multi Channel Systems, the 16 input bits
of the digital channel are not all accessible for external trigger signals, but are mostly used for
internal communication between the different components of the MEA2100-System. Only the
first four bits are connected to the physical DigIn connectors on the front side of the MEA2100
interface board. Most bits are permanently assigned to certain functions. However, these settings
can be customized if necessary. Please see the channels assignments from the following table.
Bit 0 DigIn 1
Bit 1 DigIn 2
Bit 2 DigIn 3
Bit 3 DigIn 4
Bit 4 Stimulus 1
Bit 5 Stimulus 2
